A hot water boiler therel'rom the brackets 103, which are 'tasten'ed tothe table 90 and to one of 'its flanges 91. An inlet pipe for water isindicated at 104. An inlet valve is connected to the pipe 104. An outletfaucet 106 is connected to one ol the heads oi the boiler. Piping 107 isconnected to said faucet, and a swing` joint- 108 is connected to saidpiping 107. An outlet pipe 109 extends from the swing joint- 108 andcarries the ball Heat 110. A screw plug 111. has formed therein anopening 112 liaying a valve seat at its upper end for. the safety valve113, having the counterweight 114. An outlet nipple 115 and an .inletnipple 116 are connected to the boiler 102. The nipple 115 connects withthe vertical pipe 117, which joins with the horizontal zigzag coil 118and then joins with the vertical pipe 123. The latter joins with the 102has extending return pipe 124 that leads to the inlet nipple 116. Thezigzag coil 118 is disposed to extend through the upper chambers 75, 76and 77.

An electric light socket 1,30, which can be connected to a source otelectric current is indicated with the cable 131, that leads to vthefitting 132 connected to the wall 23 of the stove. From the inner topplate or wall 55 ol the stove extend into the vchamber 75, the pair ofelectric light bulbs 135 and to the plate or wall 48, are connected thetour electric light bulbs 136, that extend into said chamber. From theplate 55, extend into portions ot the `the chamber 76, the pair oielectric light bulbs 137, and to the plate 48 are connected the tourelectric light bulbs 138, that extend into said chamber 76. To the plate55 are connected the pair of electric light bulbs 139, and to the plateor wall 48 are connected the :tour electric light bulbs 140, all ofwhich extend into the chamber 77. To the wall 23 is secured a rheostat142. Electric light switches 145, 146 and 147 are connected to the leg83 oi. the channel shaped bracket, and electric light switches 148, 149and 150 are connected to the front portion et the flange 43 oi the baseof the stove. 1n the grooves 100 of cach of the discs 99 arerespectfully located the similar resistance coils 151, 152 and 153.

Referring to Fig. 5 the wires 155, 156 are indicated to represent thewires of the cable 131, and are shown to extend from the electricbattery 157 or other source of electric current. The Wires and 156 leadto the rheostat 142. The wire 158 is connected to the wire 155 and oneend thereof extends to the resistance coil 151, and its other endextends to the electric light bulbs 135, 13e.

The switch 148 is connected to the wire 158. The wire 159 is connectedto the wire 156 and at one end leads to the switch 145 and the coil 151,while its other end leads to the electric light bulbs 136 and 135. Awire 160 is connected to the wire 155 and at one end leads Ato the coil152, and at its other end leads to the switch 149 and the electric lightbulbs 138, 137. A wire 161 'is connected to the wire 156 and at one endleads to the switch 146 and the resistance coil 152, and at its otherend leads to thc electric light bulbs 138, 137. A wire 162 is connectedto the wire 155 and at one end leads to the resistance coil 153 while atitsI other end it leads to the switch 1,50 and i'hc electric light bulbs140, 139. A wire 163 connected to the wire 156 and aL one end leads tothe switch 1-1-7 and the resistance coil 153 while at its other end itleads to the electric light bulbs 140, 139.

The plate 25L ot the door 25 may be separated therefrom and the spacelilled with heat insulating ii'iaterial not shown.

To use the cooking stove the material to be heated or cooked is locatedin requisite utensils, which are placed within the stove using theshelves 80, and the doors 25 are closet. The boiler 120 is charged withwater through the inlet pipe 104 and either one or a plurality of theelectric light switches are turned, to energize such of the electriclight bulbs and the electric resistance coils as may be required, andthe material is operated n pon until cooked.

1f it is required to draw water :from the boiler 102, the faucet 106 isopened and thc water will be discharged from said faucet. The water isled to said faucet through the outlet pipe 109 and enters the latterfrom the upper surface of the Water. By this means the het Water whichis at the top level in the boiler is first withdrawn therefrom.

Having described my invention what I desire to secure by Letters Patentand claim is:

1n an electric cooking stove the combination o1 walls therefor, one ofsaid walls constituting a top plate, electric light bulbs er:- tendinginto the stove in close proximity to said top plate, an operating tableabove .said top plate, a coil for the circulation ot water in the stoveadjacent to said electric light bulbs, piping in said table connected tosaid coil, the piping adapted to be connected to a boiler, and means toenergize said electric light bulbs, heating the water circulatingthrough said coil.

In testimony whereof I ailix my signature.
